Keyless Entry System Operation

The keyless entry system allows the driver to do the following functions from outside the vehicle by using a hand held radio transmitter:
- Unlock door locks. The courtesy lights activate automatically when using this function.
- Lock door locks.
- Release the rear compartment lid.
- Remote alarm. This feature is available only on vehicles equipped with the content theft deterrent (RPO UA6).

The transmitter operates in the UHF band. The transmitter sends digitally coded signals to the Remote Control Door Lock Receiver (RCDLR) when pressing any of the transmitter buttons.

The RCDLR detects and decodes transmitter signals. For locking, unlocking, and remote alarm commands, the RCDLR sends command messages to the Body Control Module (BCM) to operate the door locks actuators, courtesy lights, and remote alarm.

For rear compartment lid release command, the RCDLR sends a direct signal to the rear compartment lid release relay to operate the rear compartment lid release actuator.

Door lock, lighting, and rear compartment lid release systems can also be operated in the usual manner; for instance, the door locks respond to the door lock switches.

The keyless entry system can he programmed with up to four keyless entry transmitters.
